To all'whom t may concern. y

Be it known that I, DANIEL J. MURNANF,

J r., a citizen of the United 'States of America, and a resident of thecity andcountyof San'Fiancisco, Stateof California, have .in-

venteda new and useful Sash for Holding (i`rla-ss,0f.which the followingis the specification.

My invention relates to metallic sashes for holding the glass of windowsand show cases,

and particularly to sashes'for holding large.

and heavy sheets of plate glass. One of the objectsof the invention isthe'provision of a sash which' exertsno clamping action upon thevglass.Another object of the invention i's'the provisionof a sash in which theparts lare adjustably secuied together so that glass of differentthicknesses may be mounted therein.

4Other objects o f the invention together with the foregoing willbe set.forth in the follow-ing' description of the preferred embodiment ofmeans for practising the `invention and which is illustrated in thedrawings accompanying and forming part of `the Specification.- It is tobe understood that I do` not limit myself to the 'show i-ng made by `thesaid description and drawings, as I may adopt variations 'of thepreferred form-withn in the scope of my in'ventionas set forth iii theclaims. n 'Referring to the drawing, Figure `1 is a horizontal sectionalView through a sash embodying my invention, and adapted to hold twosheets of glass at rightangles. Figuie 2 is a plan view of theconformable end of the tie-bar formingpart of my sash. Figure 3 is avertical sectional View ofanotlier form of sash.

In general descriptive terms thesash'of my invention comprises astationary member adapted to engage one side of the glass, andv anadjustable member adapted to engage the .other side of the'glass. Atie-bar is secured at one end to one of' these members and the other endis of such character as to be conformable to a socket arranged .in abracket l* secured to the other member.

ing asuitably formed lieady provides means for deforming the conformableend of the tie-bar into the socket, so that thel parts are securelyinteilocked. From an inspection of Figures 1 and 3 of the drawings, itwill be perfectly obvious without special illustration A screw havthatmy invention may alsoy be incorporated in .a division baror other sash.

`More particularly and referring first to` Figures 1 and' 2` my devicecomprises a channel bar 2, preferably of metal andsuitably held at itsends by devices of'a well known 'character' which .need not bevdescribed here. Forming an edging strip or molding. for

both edges of the channel 2 isa metal plate',

able member. of the sash comprises the vmold- .l

ing or plate'f'? Whichlis adapted tol engage. the sheetsV of glass 4Lland 5 on thev sides opposite those' engaged bythe-molding 3.

the adjustable member of t-lie sash to'tlie sta;-4

tionary member.l Rigidlyv secured at one j 4againstwhich the two'sheetsof glassflf and 5 areladapted to lie.

Means are provided for rigidly `securing end tothe adjustable sashmember is a tie`- bar 8, extending inwardly tlirouglisuitable aperturesformed in the molding 3 into'tlie' channel 2. .As many tie-bars asdesired may be used and I prefer to space them aboutv every 8 incheslongitudinally of the s'asl'i.

The innerfree end of each tie-bar is shownf in plan in Figure 2. The endis formed ,with Ia slot 9, the edges of the bai' bordering the slotbeing serrated by means of short slits or'notches 11 closely spaced inthe edges.v

These serrated edges render the end of the tie-bar conformable. j Thenthe sash is assembled this end of each f the"tiebars,is adapted to-overlie a bracket 12, riveted ir otherwise rigidly secured on theinside of the channel 2. Threaded intoA each'bracjket is 'a screw 13,that portion surrounding the,l screw 1 being'conically depressed toforma socket 14. The underside 15 of the head of the screw is of conicalform con'iplemeiitary to .the socket. The screw is adapted to extend fthrough the slot 9 of the tio-bai, and when vtightened down, theserrated edgesof the bar are deformed bythe conical head soithat..

bracket :iretheii rigidly inteilocked.`

It will be obvious fromthis construction that the adjustable member ofthe sash may be rigidly secured to the stationary member without theleast clamping action being exerted on thev glass; and lweaiisc of thxwide itlicyseat in `the socket, and ',tiefbarl and "adjustability,give-n by the slotted end of the tiefbar, glass of varying thickncsses.may be held, it being merely required to seat the glassagamst the mnermolding,

and press the outer molding against the .glass' i' r.for tu'rningthescrew.

One of the greatest causes of. broken plate glasslie in stresses exertedon the glass by the sash members. lVith such stress exerted by themounting of the glass, wind pressure and vibration which otherwise woulddo no harm' is frequently destructive. It Will'be l observed thatmy sashmembers are inter- -lockedwith perfect security and Withno tendencygtodraw out of posit-ion so as to exert unrecognized pressure' upontheglass.

' It Will benoted that the" fasteningdevices of my sash are. includedwithin the moldings and channel. Therefore, -in order to'pro'vide accessto the'screwl 13 of each bracket, small apertures 16 are' formed atsuitable intervals inf the side .Wa-ll of the channel 'to permittheinsertion"ofv a tool j-Means are also provided for preventing `the lossof the screw v13 prior'to the asl"sembl'ing of the saslnfand I'accomplish this by making the screw 13 of such a'length that l lits headengages the inner wall of the chan- A nel before'its shank disengag'esthe bracket in which it is. threaded. The screw 1s threaded' into thebracket before the bracket is mounted in the channel, and lafterSt-heassembling of the bracket in the channel, the screw cannot be turned'out of the bracket; The tie-bars are Vreadily 1 released Vbyloosening'the screwsl, and eventhough a different thickness of' glass isthen placed4 in jthe saslnthe' conformable nature ofthe tieening downofthe screws,v v
